Full Discussion: Extract particular folder from a .tar format files.

What Operating System and version you you have?
What Shell do you use?

Do you have the "pax" command? It's a program which can read "tar" archives.

What was the command used to create the "tar" archive?

How large is the archive, and how many different files need to be restored?
Quote:
ls -ald backup.tar
What do some sample filenames look like:
Quote:
tar -tf backup.tar
Do you know that if the archive was created with absolute pathnames you can only restore to exactly the same directory with "tar"?

Why so many questions you may ask? Restoring from a "tar" archive is inherantly dangerous.


The generic answer based on what we know so far is:
Code:
tar -xvf backup.tar '/root_folder/Folder1/Folder1-2'

Do test the command syntax in a test server with expendable files and be aware that the target folder and subfolders will be overwritten.

bf_tar

BF_TAR(1)																 BF_TAR(1)

NAME

       bf_tar - shell script to write a tar file of a bogofilter directory to stdout

SYNOPSIS

       bf_tar [-r] [-R] bogofilter_directory

DESCRIPTION

       bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
       EXAMPLES below).

OPTIONS

       The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
       files.

       The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
       is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.

EXIT STATUS

       The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.

EXAMPLES

       o  bf_tar ~/.bogofilter > outfile.tar

	  Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.

       o  bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz

	  Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.

       o  bf_tar `pwd`/mydirectory > outfile.tar

	  Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.

NOTES

       This script is meant for use with Berkeley DB based bogofilter versions.

       This script requires a SUSv2 compliant pax utility.

       This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
       that /usr/xpg4/bin/sh can be used.
